Australian pair Nick Kyrgios and Thanasi Kokkinakis have gained entry into the ATP Finals as a doubles partnership for the first time.
Neither player has competed in the season-ending tournament, which brings together the year's best men's players in the singles and doubles.
But they are the fifth of eight pairings to join the doubles field after a year in which they claimed their first major at the Australian Open and the Atlanta Open crown, while Kyrgios added a title in Washington alongside American Jack Sock.
Kyrgios and Kokkinakis played seven tournaments together this year, finishing with an 18-5 win-loss record.
They are the first all-Australian pair to compete at the event since Wayne Arthurs and Paul Hanley in 2005, when it was called the Tennis Masters Cup.
The Greek Australian pair got the nod for the ATP Finals because they won a grand slam title and neither world number 14 Kyrgios nor 17th-ranked Kokkinakis can be caught in the rankings by fellow Australians Matt Ebden (31st) and Max Purcell (37th), who were beaten in the Australian Open final before going on to win Wimbledon.
